Work: Calculate the value of equation 1.2×1.5×44+0.7×2.1×19+0.7×1.5×1+1.5×1.5×2 .
Question type: Mathematical calculation
Solution:
1.2×1.5×44+0.7×2.1×19+0.7×1.5×1+1.5×1.5×2
=1.8×44+0.7×2.1×19+0.7×1.5×1+1.5×1.5×2
=79.2+0.7×2.1×19+0.7×1.5×1+1.5×1.5×2
=79.2+1.47×19+0.7×1.5×1+1.5×1.5×2
=79.2+27.93+0.7×1.5×1+1.5×1.5×2
=79.2+27.93+1.05×1+1.5×1.5×2
=79.2+27.93+1.05+1.5×1.5×2
=79.2+27.93+1.05+2.25×2
=79.2+27.93+1.05+4.5
=107.13+1.05+4.5
=108.18+4.5
=112.68
Answer:1.2×1.5×44+0.7×2.1×19+0.7×1.5×1+1.5×1.5×2=112.68
